1 all whom it may concern.-

Be it known that I, FREDERICK B. MARVIN, a citizen of the United States, residing in Paterson, county of Passaic, and State of useful Improvements in Compositions of Matter for Building Purposes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as it appertains to make and use the same, reference being had to the accompanyin drawings, and to letters of reference marke thereon, which form a part of this specification.

My invention relates to concrete and other artificial-stone substances; and it has for its object to provide in lace of the usual composition of matter 0 this nature, in which cinders or broken stone forpg theffsolidf inments. The solid ingredient of substances of this nature as heretofore compounded beitself in masses of the smaller particles, only the lar er pieces standing properly dispersed t rough the substance. This affected materially the homogeneity of the substance and led to unevenness of strength and a lack of the desired elasticity, porosity, &c., in the mass. By providing regularly-sized solid disadvantages and besides have a material which is more readily handled and more at the command of the workmen in the matter of their perceivin just what quantity and dis osition of solids is needed and attained, an i ing ala diamanaantionali form an especially of angular 6m the and in addition the knit more firml with the substance with wliic li tli y ai e mixed and are capable of being conveniently acked in the loose state for shipping in smal space and complact arrangement, and by further 22. 2% t emb die -95 1 9122..tliali h ne f gie mas ifhenthey are incorporated thereiii s gn ased withou t detracting frgrg j,besidesincrea'ing the'porosity and the 1m erviousness to spunds, heat, and cold x 14 If-J 1.-,. :MMTQK incl en here 0.

Specification of Letters Patent.

Application filed January 30,1905. Serial No. 243,260. 7 7 76 Patented Aug. 22, 1905.

trated in the accompanying drawings, where- Figure 1 is a sectional view of concrete or the like containing my conventionallyformed and cellular bodies, and Figs. 2 and 3 are sectional views of two different forms of said bodies.

The lastic ortion a of the concrete may be made up of any suitable materials. In it is mixed while still in the plastic state the blocks shown in Figs. 2 and 3. Said blocks (designated 1) in Fig. 1) may be formed in any suitable manner not necessary to be described in detail herein. In a copending application filed of even date herewlth I have indicated how said blocks may be formed. Suffice it to say that the blocks are of approximately the same size and conventional and preferably substantially the same in shape. They are, furthermore, formed with cells 0. These cells may be either one to a block, as in Fig. 2, in which case they approximate in size the size of the block, or several to a block, as in Fig. 3. The cells may be either entirely closed, or substantially so, the idea being to at least reserve the cellular structure after the blocks are incorporated in the concrete against being filled by the concrete. In order to augment the adhesion or binding between the blocks and the cement the former may be corrugated on the outside, as at d, or otherwise formed with an uneven surface.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

1. A composition of matter for building purposes comprising plastic material an locks of refractory material of "conventional form and substantially regular size inters ersed in said I lastic material, substantia y'as described 2. A composition of matter for building purposes comprising plastic material and blocks of refractory material of conventional and angular form and substantially regular size inters ersed in said plastic material, substantially as described.

3. A composition of matter for building purposes com rising plastic material and locks of cellu ar refractory material of conventional form and substantially regular size interspersed in said plastic material, substantially as described? closed cell approximating in size the size of the block, substantially as described.

In testimony that I claim the foregoing I 1 have hereunto set my hand this 17th day of January, 1905.
